MATLAB绘制GIF格式的动态点和动态曲线随动

代码如下

clc;clear;close all;
fig=figure;
axis([0,2*pi,-1,1]);
x=linspace(0,2*pi,20);
y=sin(x);
h=animatedline("Color",'r',"Marker","o","MarkerSize",10,"LineWidth",3);
im=cell(1,length(x));
for i = 1:length(x)
  addpoints(h,x(i),y(i));
  drawnow
    frame = getframe(fig);
    im{i} = frame2im(frame);
end
filename = 'C:\Users\13349\Desktop\BILIBILI稿件\MATLAB动图\MATLAB1_3.gif'; % Specify the output file name
for idx = 1:length(x)
  [A,map] = rgb2ind(im{idx},256);
  if idx == 1
    imwrite(A,map,filename,'gif','LoopCount',Inf,'DelayTime',1);
  else
    imwrite(A,map,filename,'gif','WriteMode','append','DelayTime',1);
  end
end
